I've enabled remote administration. When accessing the "Web Address for Management" I see the typical login screen. Once logged in, I'm presented with the page below.

Please note, I am doing this over a VPN connection (TunnelBear).

Are there known HTML loading issues when using remote management? If your response is that the VPN is causing this, then feel free to convert this to a Bug Report and to fix your issue related to remote management over VPN.
